How to remove the rogue Cent Browser from your operating system?
Written by Tomas Meskauskas on (updated)
What is Cent Browser?
Cent Browser is an untrustworthy browser based on the Chromium open-source project. It has been observed operating as adware, and it also promotes the internet-start.net fake search engine - which is a browser hijacker trait. Since most users install Cent Browser unintentionally, it is also classified as a PUA (Potentially Unwanted Application).
Cent Browser adware in detail
Adware enables the placement of pop-ups, surveys, banners, coupons, surveys, full-page, and other intrusive advertisements on visited websites or different interfaces. The displayed ads negatively affect the browsing quality and pose a threat to device/user safety.
These adverts endorse various untrustworthy, deceptive/scam, and even malicious sites. Some intrusive advertisements can infiltrate software (e.g., PUAs) into systems - upon being clicked.
Cent Browser has been noted promoting the internet-start.net fraudulent web searcher. This is how browser hijackers operate - they assign the addresses of their search engine' as browsers' homepage, default search engine, and new tab/window URLs. Hence, new browser tabs/windows opened and search queries typed into the URL bar - redirect to the promoted address (e.g., internet-start.net).
Fake web searchers are seldom capable of providing search results, and if they can - the results are inaccurate and may promote dubious/malicious content. Since these web searching tools typically cannot - they redirect to Google, Yahoo, Bing, and other genuine search engines.
Most PUAs (adware included) collect users' browsing activity and personally identifiable information, which can then be monetized by being shared with and/or sold to third-parties. To summarize, the presence of unwanted software on devices can lead to system infections, severe privacy issues, financial losses, and identity theft.

Rogue browser examples
ShieldBrowser, Gate, InLog, and WebDefence are some examples of rogue browsers. Nearly all PUAs (e.g., untrustworthy browsers, adware, browser hijackers, etc.) appear legitimate and offer "handy" functionalities, which are seldom operational. Functionality and user safety are irrelevant, as the only aim of unwanted applications is to generate profit for the developers.
How did Cent Browser install on my computer?
Select PUAs (e.g., Cent Browser) have "official" promotional/download sites. These apps are also proliferated using the "bundling" technique - packing regular programs with various supplements. Rushed downloads/installations increase the risk of allowing bundled content into the device. Intrusive advertisements are used to distribute PUAs as well. Once clicked on, the adverts can make downloads/installations without user consent.
How to avoid installation of potentially unwanted applications?
It is highly recommended to research software and download from official/verified channels. Untrustworthy sources, e.g., unofficial and freeware sites, Peer-to-Peer (P2P) sharing networks, etc. - often offer bundled/dangerous programs and media.
When downloading/installing, it is advised to read terms, study available options, and use the "Custom/Advanced" settings to opt-out from all additions. Intrusive ads appear harmless, yet they redirect to various unreliable/questionable sites (e.g., pornography, adult-dating, gambling, etc.).
In case of encounters with adverts and/or redirects of this kind, the device must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with Cent Browser, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
